London Bombings: Why We Are Glued To The TV

Since the terrorist attacks in London yesterday, we have all been glued to the TV for the latest news. The images and stories of blood splattered survivors and long shots of those less fortunate have shocked and saddened us. And yet we can’t look away, despite the fact that research suggests that watching may cause Post-Traumatic Stress Disorder. Why do we seek out images and reports that are likely to be upsetting and perhaps disturbing?

Keinan, Sadeh and Rosen (2003) outline three psychological theories that help to explain this strange desire. Information seeking theory suggests that uncertainty causes conflict and increases arousal, so finding out what is going on reduces uncertainty and therefore reduces arousal. Safety signal theory places the emphasis on delineating safe from unsafe periods of time. We are continually asking ourselves whether the storm has blown over yet, whether it is safe to go outside or enter the danger zone. A final theory suggests that information gives us a sense of control over an event, even though it is essentially beyond our control.
